FIELD: chemistry.
SUBSTANCE: invention relates to protection of the environment and is aimed at reclaiming soil contaminated with heavy metals and petroleum products. The composition has a base in form of natural silica gel and an autogenous mono-prismatic mineral from a group of layered hydrous silicates - glauconite, and mineral fertiliser - urea, with the following ratio of components, wt %: natural silica gel 30.0; glauconite 69.7; urea 0.3.
EFFECT: possibility of using the composition on different type of soil contaminated with heavy metals, as well as petroleum products, high capacity of the composition for adsorbing contaminants with considerable reduction in toxicity.
